What the declared salt would weigh
Natural Rhythm Magnesium Taurate declares 150 mg of elemental magnesium per serving in NIH DSLD 271261, requiring 1,694.92 mg of magnesium taurate under the salt model calculated 2026-09-13.
| Step | Value | Evidence |
|---|---|---|
| Declared elemental magnesium | 150 mg per serving | observed · label 2022-07-21 |
| Resolved salt | Magnesium taurate · full-record | computed · name resolved from filed text |
| Reference formula | Mg(C₂H₆NO₃S)₂; 274.58 g/mol | computed · chemical reference |
| Elemental fraction | 8.85% by mass | computed |
| Compound mass per serving | 1,694.92 mg = 150 mg ÷ elemental fraction | computed |
| Compound mass per discrete unit | 847.46 mg | computed |
At powder density 0.6–0.8 g/mL, 847 mg of powder requires the largest standard size, 000 (holds about 1,100 mg).
The verdict uses the most favourable reading for the product — the smallest compound mass the label allows. It excludes the shell and other ingredients; their unreported masses are not added as guesses.
Size 0 holds about 545 mg, size 00 about 730 mg, and size 000 about 1,100 mg at powder density 0.6–0.8 g/mL. These are model inputs, not measurements of this product's capsule. Read the mass-budget method.

Magnesium lines as filed
Natural Rhythm Magnesium Taurate retains 1 magnesium-related rows in NIH DSLD 271261, including 1 rows selected for the primary serving, from label 2022-07-21, examined 2026-09-13.
| Filed amount | Serving order | Filed salt / notes | Calculation role |
|---|---|---|---|
| 150 mg | 1 | Salt not identified in this row as of 2026-09-13 From | Selected primary serving |
The elemental amount comes from the selected magnesium line. A salt named under another nutrient does not make that nutrient's quantity an elemental magnesium value. Distinct unresolved primary amounts remain ambiguous; they are not added together.

What the package works out to
Natural Rhythm Magnesium Taurate works out to 60 days per package at the label's own serving and filed frequency of 1 servings per day, according to label 2022-07-21, calculated 2026-09-13.
| Net contents as filed | 120 Capsule(s) |
|---|---|
| Discrete units in the package | 120 |
| Serving size as filed | 2 Capsule(s) |
| Units per serving | 2 |
| Servings per package | 60 |
| Daily servings in the label instructions | 1 |
| Days per package at the label's own serving | 60 days |
Days = filed servings per container ÷ filed servings per day. If the label gives a frequency range, the largest frequency gives the shortest duration. Cost per serving = observed item price ÷ filed servings; cost per label-day multiplies this by the filed frequency. This follows the label's own instructions; it is package arithmetic, not intake advice.
Benchmark · 6 observed prices in taurate
A same-salt reference for this package
At the median cost per 100 mg observed across 6 taurate labels ($0.1673), a package of this size (9,000 mg elemental in Natural Rhythm Magnesium Taurate) would correspond to $15.05, using observations from 2026-09-11 to 2026-09-11, calculated 2026-09-13. This is a benchmark, not a retailer quote.
| Salt and number of observations | Magnesium taurate · n = 6 |
|---|---|
| Median observed cost per 100 mg | $0.1673 |
| Filed elemental magnesium per package | 9,000 mg |
| Benchmark package equivalent | $15.05 = median EC100 × package elemental mg ÷ 100 |
| Evidence tier | benchmark · calculated 2026-09-13 |
The median is the middle sorted observation, or the average of the two middle observations for an even group. Each label contributes one observation. This value is neither an offer nor an estimate of a specific retailer's current price.
Percent daily value · observed and computed
The label's percent daily value, recomputed
Natural Rhythm Magnesium Taurate files 1 magnesium percent-daily-value entries in NIH DSLD 271261; the check below applies the group-specific references in 21 CFR 101.9 to its 150 mg primary serving, calculated 2026-09-13.
| Group as filed | Declared | Reference | Recomputed | Difference |
|---|---|---|---|---|
| Adults and children 4 or more years of age | 36% | 420 mg | 36% | 0 percentage points |
Percent daily value = declared elemental mg ÷ the group's reference mg × 100, rounded to an integer. The adult and age-four-plus reference is 420 mg. Historical labels can use earlier references; a difference does not establish a filing error. Full-record entries may cover multiple serving sizes, so this table identifies the primary-serving basis explicitly. Group references and interpretation.
